K Street Project, Delay's "Pay to Play," Abramoff's influence peddling machine, Cheney's no-bid contracts for Halliburton (KBR), and most recently Rod Blagojevich's dreams of lucre and/or influence from naming a successor to Obama's Senate seat, are all part of the disgusting, but pervasive culture of money and influence in American politics (of all stripes) and indicative of the unease that Obama's fund-raising methods may have engendered in the traditional influence-peddling/lobbyist-buying circles in DC.
